After the last named operation, the flar- A ings of metal are trimmed off, and in the 1 final operation, the finish sizing andshap- ,ing of the curved p'intle bearing portion of the hinge butt is formed after which the aperture for-receiving the pintle pin 26 is drilled through the bearing 23 and the side faces of said bearings cleaned off .by a suitable tool to render the same smooth and of perfect alinement to function with the I knuckles 14', it being also understood that the recesses at the opposite sides of the bearing 23 may also be cleaned out for this "purpose ifthe same is found to be necessary.

The offsetting of the shank 27 of the butt,

p as represented in dotted lines in Fig. 4 and full lines in Fig.7, may be performed if defs'ired in the several operations of forming the hinge butt 15, and if so fashioned, it I I sides of the bearing 32 closing the recesses will be understood that the shank is returned to proper position after the butt has i been completely formed.

workpiece be heated, it will be understood that the entire curved end portion of the 'hinge' butt and particularly the bearing 23 thereofwill be formed into substantiallya solid unitary mass, while if i the same is formed cold, the metallic mass will be compactly swaged or pressed together under pressure inth'e proper shaping of the hinge In Figs. 9,10 and 11, I have showna slight modificationin the formation ofthe hinge butt 15 wherein the bearing '23 is formed by a plurality of independent members 28 rather than from the tongue 18, and in this construction, in addition to the butt I 15 which will constitute one part only of the butt,is employed ashell or facing'member 29. Thefparts or extensions 24 of thestruc- 'ture shown in Figs. 1 to 8 inclusive are not' employed, said facing having a hood'portion whichtakes the place of the members'24l "The-"structure shown in Fig. 11is substant-ially the same as that shown and described in Patent No. 1,477 ,193, granted to me De 'cember 11, 1923, with the exception that the bearing portion 31 of the hinge butt formed by the members 28 is of greater strength due to the method of itsformation which will be the-same as that described in connection with the butt shown in Figs. lto 8 inclusive. In Figs. 12 and 13,1 have shown-another 'able tool 'if required.

modification in which'a blankv similar to that shown at 16 in Fig. 2 ofthe'draw ng is employed,the cut out portions 17 being cut deeper into the material of the blank to form a longer tongue 18 and to increase the rolling, orturning operaton on the blankto such a degree as to provide throughout the entire curveden'dv portion of the hinge substantially two thicknesses of metal, the beveled end portion 19 extending to'such a point as to provide substantially two complete turns ,ofthe-tongue member 18.--'After-the blank has been formed substantially in the manner illustrated in Fig. 12 of the drawing, the same is preferably heated and then placed indies which will shape the curved end portion of the hinge into a form substantially'similar to that illustrated in'Fig.

13 of the drawing forming a large, heavy pintle bearing 32, the inner edge of'which extends to the top face 33 of the butt as shown'at 34, reinforcing and strengthening the bearing 32 at this point. Recesses 35 will be formed atfthe opposite sides of the bearing32 similar'to the structure shown in Figsf 5 and? of the drawing, being adapted to receive the knuckles of the other butt of-the hinge, while the butt is extended nd gradually reduced tofform p ject'ing' hood members 36 at-the opposite 35'-and enclosing or partially enclosing the free edges 37of the hood members 34 constituting a stop for limiting the movement 38' and the recesses 35 and side faces of the said recesses knucklesof the other-butt of the hinge, the In the above described method, if the bearing 32 may be cleaned out by asuit- I i lustrated in the accompanying drawing, it will be apparent thatthe pintle bearing of the hinge butt will be madevery strong and durable and capable of withstanding the It will also be seen llli greatest stress or stresses and will be as 3 strong as, or even stronger than hinges of this class fashloned from castings, forgings and the like and may beproduced at much constructiomit willbe understood that my invention 1s notlimited' in these respects and various changes in and modifications of'the method herein set out. may be made-within less expense as compared with the other methods of forming hinges of this class, and

the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, What I claim as new and desire to secure by Letters Patent, is

1. The herein described method of fashioning a hinge butt from sheet metal to provide at one end of the butt a curved hood portion with a pintle bearing Within said hood portion, which consists in providing a rectangular sheet metal blank, cutting out the corner portions of said blank to form a projecting tongue at one end thereof, curling said tongue and adjacent end portion of the blank to curl the tongue upon itself a number of times to form a thick cylindrical member and a curved hood portion partially encircling said member and extending at opposite sides thereof, and then compacting said cylindrical member to form a substantially solid pintle bearing within said hood member.

2. The herein described method of fashioning a hinge butt from sheet metal to provide at one end of the butt a curved hood portion with a pintle bearing within said hood portion, which consists in providing a rectangular sheet metal blank, cutting out the corner portions of said blank to form a projecting tongue at one end thereof, curling said tongue and adjacent end portion of the blank to curl the tongue upon itself a num-' ber of times to form a thick cylindrical member and a curved hood portion partially en circling said member and extending at opposite sides thereof, then compacting said cylindrical member and hood portion to form a substantially solid pintle bearing within said hood member, and forming in said compacting operation recesses in said hood portion and at opposite sides of said pintle bearing to receive the knuckles of the other butt of a hinge.

3. The herein described method of fashioning a hinge butt from sheet metal to pro-v vide at one end of the butt a curved hood portion with a pintle bearing within said hood portion, Which consists in providing a rectangular sheet metal blank, cutting out the corner portions of said blank to form a projecting tongue at one end thereof, curling said tongue and adjacent end portion of the blank to curl the tongue upon itself a number of times to form a thick cylindrical member and a curved hood portion partially encircling said member and extending at opposite sides thereof, then compacting said cylindrical member and hood portion to form a substantially solid pintle bearing within said hood member, and forming in said conipacting operation recesses in said hood portion and at opposite sides of said pintle bearportion.

ing to receive the knuckles of the other buttadjacent portion of the blank to form a cylindrical member of greater thickness than the thickness of the blank and a'hood portion partially encircling said member and extending at opposite sides thereof, heating the blank thus formed, and then swaging said cylindrical member to form a substantially solid pintle bearing within said hood 5. The herein described method of making the butt of a hinge which consists in providing a sheet metal blank having at one end portion thereof a projecting member of less tranverse dimensions than the remainder of the blank, curling said member and adjacent portion of the blank to form a cylindrical member of greater thickness than the thickness of the blank and a hood portion partially encircling said member and extending at opposite side-s thereof, heating the blank thus formed, and then swaging said member and hood portion at the opposite sides of said member to form of said lOO cal member. of greater thickness than the.

thickness of the blank and a hood portion partially encircling said member and extend ing at opposite sides thereof, heating the blank thus formed, and then swaging said member and hood portion at the opposite sides of said member to form of said member] a cylindrical pintle bearing and recesses in the hood portion at the opposite sides of said bearing, the walls of said recesses being of less thickness than the metal of the blank, v

and, forming in said swaging operation, a

stop shoulder on the pintle bearing portion of the butt and in alinement with the free edge of the hood portion.

In testimony thatI claim the foregoing as my invention I have signed my name this 13th day of March 1925. Y
